Abstract

To use composites in design of car components, their mechanical properties are for a great importance. A calculation of the stresses and loads of parts manufactured from composites can be carried out. To determine their mechanical properties, theoretical models can be used. Bearing in mind the differences in the charges of composite materials, even when the same manufacturer produces them, an experimental research is required on these materials. Within this paper, mechanical properties of glass fiber-reinforced HDPE and LDPE as well as carbon fiber-reinforced epoxy resin have been determined experimentally using three-point bend tests..
